made available adequate means for purging most effluents of their poison. Of all the sugar factories in England, the one whose experi- ments offer most hope for the future of the industry is at Eynsham near Oxford. The effluent that drains out into the Thames (as the Thames Conservancy make sure) would not offend, much less damage, the most sensitive' member of the - sensitive race of trout. The ingenious and uncostly slicing and drying experiments at Eynsham (undertaken in co- operation with Oxford) have progressed satisfactorily, and promise to make a cardinal difference to the industry, both by lengthening out the period of activity in the factories and cheapening the process.
